NAME

6       HPL_dlaswp02N - pack rows of A into columns of W.

SYNOPSIS

9       #include "hpl.h"
10
11       void  HPL_dlaswp02N(  const int M, const int N, const double * A, const
12       int LDA, double * W0, double * W, const int LDW, const  int  *  LINDXA,
13       const int * LINDXAU );

DESCRIPTION

16       HPL_dlaswp02N  packs  scattered rows of an array  A  into workspace  W.
17       The row offsets in A are specified by LINDXA.

ARGUMENTS

20       M       (local input)           const int
21               On entry, M  specifies the number of rows of A that  should  be
22               copied into W. M must be at least zero.
23
24       N       (local input)           const int
25               On  entry,  N  specifies the length of rows of A that should be
26               copied into W. N must be at least zero.
27
28       A       (local input)           const double *
29               On entry, A points to an array of dimension (LDA,N).  The  rows
30               of this array specified by LINDXA should be copied into W.
31
32       LDA     (local input)           const int
33               On  entry,  LDA specifies the leading dimension of the array A.
34               LDA must be at least MAX(1,M).
35
36       W0      (local input/output)    double *
37               On exit,  W0  is  an array of size (M-1)*LDW+1,  that  contains
38               the  destination  offset  in U where the columns of W should be
39               copied.
40
41       W       (local output)          double *
42               On entry, W  is an array of size (LDW,M). On exit,  W  contains
43               the   rows  LINDXA[i] for i in [0..M) of A stored  contiguously
44               in W(:,i).
45
46       LDW     (local input)           const int
47               On entry, LDW specifies the leading dimension of the  array  W.
48               LDW must be at least MAX(1,N+1).
49
50       LINDXA  (local input)           const int *
51               On  entry,  LINDXA is an array of dimension M that contains the
52               local row indexes of A that should be copied into W.
53
54       LINDXAU (local input)           const int *
55               On entry, LINDXAU  is an array of dimension M   that   contains
56               the  local   row indexes of  U that should be copied into A and
57               replaced by the rows of W.
